Servicing & Maintaining the Temp. Cartridge
Sedimentation in the water will clog the filter screens around the cartridge.
This is also true especially in new installations. To maintain and clean the
mixer cartridge, follow the instructions below:
1 Shut off water supply on the main water inlets, or the integral stop/check
valves on both inlets .
2 R
emove the temperature handle assembly
Å - É by using a hex wrench
and removing the set hex set screw Ç and the temperature limit stop Ñ.
3 U
nscrew the cartridge using adjustable wrench with smooth flat jaws.
Rinse the strainers around the cartridge under running water or leave
to soak in vinegar or de-scaling agent.
4 Before re-assembling cartridge, clean its housing with wet cloth and lubricate
the o-rings around the cartridge.
5 Re-assemble cartridge into body.
6 Replace the stepped plastic temperature limit washer Ñ according
to the drawing and turn spindle A until you reach required temperature
100.4ºF (38ºC).
7 R
eplace the temperature control handle.
Before You Begin
Hot Water Supply Temperature . Maximum inlet hot water temperature is 185ºF
(85ºC) and the minimum inlet cold water temperature is 41ºF (5ºC). The recommended hot water inlet temperature is 149ºF (65ºC). The minimum temperature
difference between the hot inlet water temperature and the mixed tempered water
temperature is 50ºF (10ºC).
B
A
Operating pressure . The recommended maximum inlet water pressure is 75 PSI
(5 bar). Minimum water inlet pressure is 1.5 PSI (0.1 bar). Piping should installed
properly to maintain a balance between Hot and Cold inlet operating pressure to
maintain maximum efficiency and consistent mixed water temperature. When water
pressure exceed 75 PSI, a pressure reducing valve needs to installed upstream of the mixer.

Installation information
See the installation depth guide on the plastic mud guard for minimum and maximum wall depth installation. The mixer is furnished with a maximum temperature
limit stop set at 10 9.4ºF (43ºC). Mixer inlet and outlet ports are ¾” NPT. The bottom
outlet may be used for a bath spout or plugged with a standard ¾” NPT pipe plug.
A separate shut off valve must be used in conjunction to control on/off function and
flow control. A temperature variation will occur if water is dually supplied by both
the top and bottom port at the same time.
Plumbing recommendations
· Large runs of pipe work will cause frictional loss of pressure.
· Flush all piping thoroughly before installing the valves to prevent clogging of filter
screens.
· Ensure adequate supply of both hot and cold water can be maintained.
building code compliance. The mixing valve complies with ANSI/NSF61 standard
and should be installed in compliance of local building codes.
Before Removing the Cartridge
Screw the 2 threads of non-return valve before
removing the cartridge (see drawing). In case of
reduction of flow rate, close the two main inlets and
check if the filter at the bottom of the non-return
valves are dirty, in this case clean them.
Servicing & Maint. Integral Stop/Check Valves
otating the 2 screws on the stop/checks will shut off the water to the cartridge
R
for service and maintenance. If you are experiencing a reduction of water
flow to the mixer, you may have an obstruction of debris in the check valve
or in the strainer at the bottom. Shut off the water for both the hot and
cold at the main inlet; remove the stop/check assembly. Clear the strainer
and check valve of any debris and replace back into the inlets. This should
be done before removing or servicing the cartridge. Be certain to fully
open the integral stop after service.

Care/Cleaning of Your Product
After installation, the finished trim portion should be maintained by wiping with a soft, damp, clean
cloth and then polished with a dry dust cloth. Never use abrasive cleansers or detergents. Cleaners
containing alcohol, acid or corrosive chemicals should not be used. Some household bleaches and
denture cleaners can damage the finished pieces, and if splashed onto the trim, it should be
immediately washed off with cold water.

If these instructions are followed, the fitting will give many years of satisfactory use. There is a policy
of continuous improvement and the manufacturer reserves the right to change specification without
notice.
